LUBRICATIN G DEVICE.

Application filed November 6,1915, Serial N o. 59,989.

To all 'whom t may concern Be it known that I, MELVILLE F. WEBSTER,

a citizen of the United States, residing at Rockville Center, in the wcounty ofv Nassau and State of New York, have invented a new and useful Lubricating Device, of which the following is a specification. Y Y

This invention relatesto lubricating devices, and is designed morey particularly for use in connection with elevator guideY rails, although capable of more extended use.

.The object of the invention is toprovide an oiling device which will supplyoil to the guide rails only when the elevatorA is in motion and will return all excess ofV oil to the reservoir, besides maintainingv the oil in a clean condition. I l Y In accordance with the present invention, an oil container, oil being considered as the lubricant used, is mounted on the elevator adjacent to each guide rail, and vjournaled in the reservoir so as to project therefrom into contact with the guide rail isa roller. The mounting for the roller is so arranged as to readily yield to side movements of the elevator with respect to the guide rail Vand to have a constant tendencyto gravitatetol` lward the side rail while the roller serves as a propelling means for an oil elevating structure entering the body of lubricant in the body of the reservoir or container and lifting such oil to the roller. Furthermore, provision is made for ready access to the interior of the reservoir and to the journal bearings of parts therein so that the reservoir and turning partsv may be cleansed when needed and fresh lubricant supplied as occasion demands.

The invention will"l be best` understood from a consideration of the following detailed description, taken in connection with the accompanying drawingsfforming partV of this specification with the further understanding thatV while the drawings show a practical form of the'invention, the latter is not conned to any strict conformity with -the showing of the, drawings, but may be changed and modified so long as such changes and modifications come within vthe scope 'of the appended claims.

In the drawings F igure 1 is a vertical section through the lubricant reservoir showing the adjacent guide rail for the elevator in elevation. Fig. 2 is a plan view of the reservoir with the top plate removed Specicati'on of Letters Patent. l

and the guide rail shown in cross section. i

3 is a section on the/line 3-3 of Fig. 2 'with the movingl partsy omitted. Fig.` 1 is a sectlon on the line lf-4 of Fig. 3.

Referring' tothe drawings, thereis shown a guide rail 1, which rail is of customary T form 1n cross section. v

Mounted on the elevator, which latter is A not shown in the drawings, adjacent to each guider'rail 1, is aco-ntainer or reservoir 2, the container shown 1n 'the drawings beingof substantlally square cross `section and elongated in the direction of its length butrsu'ch l particular shape is not at all obligatory. yAt' the upper end, it being understood that the container Yis customarily installed upright,v

there-is a projecting neck 3 forming a ma-rprovided with the passage 7 will be considered as the front of thecontainer. p j On the inner wall of opposite sides ofthe neck 3, l recesses 8 are formed by surrounding for the corresponding end of a rod 11 extending across lthe reservoir 2 from side to side, and normally lodged in the recesses 8 is a rod 11 extending across the reservoir.'

erably of wicking, of a lengthv to reach close to the'bottom of the container .2, whichV lubricant is ofany desired nature andas it should be normally liquidany suitable lu-V l lbricating oill may be used and consequently for convenience of description, the .term oil The neck 3 closeto'the front ofthe reser-I vi-voirl hasangle recessesy lffdefinedby flanges The angle recesses 14, have rounded s V,bottom ends 16 seating corresponding ends of a` rodl 17 carrying at itsv central portion spacedarms 18-having angle extensions 19 extending on opposite sides of the web 12 A and .at the ends'remote fromv the arms l18 provided withk a junction piece 2O which may or may not be integral therewith.

9o-V Therod 1l carries an endless web 12 prefgravity. This tendency Y Furthermore,

Mounted in the angles Vof the armsV 18, 19 is a pin 21 carrying a roller 22 between the arms 18, said roller being of a size to eX- tend through the passage 7, and bear against the stem member of the TV guide rail 1, which member is the active guiding tread of the guide rail. The roller 22 is preferably, however, not necessarily made of ber such as vulcanized fiber, but may Vof course be made of other suitablev material.

Tn the normal position of the reservoir 2 with relation to the guide rail 1, which position is somewhat closer than illustrated in the drawings, the junction end V20, of .the

arms 19 is suciently raised to cause the arms 19 to extend at a vslight rising angle toward the back of the reservoir while the arms 18 have a corresponding angle to the vertical. There is therefore a constant tendency for the roller or wheel 22 to bearv occurs in the running of an elevator.

In practice the space between the front of the, reservoir and the guide rail may be Y about of an inch but when'the arms 1S areY parallel with the front of the reservoir, such space will be about of anl inch, wherefore Y considerable margin is providedrfor side movement of the elevator withv relation to the guide rails. -The pin Y11 supporting therwick may revolve, that is it actas a wheel, but by using a pin excessive speed Vof movement of the wickis prevented.

. While a vulcanized fiber oiling wheel 22 has been referred to, it willbe understood that it may be constructed of other materials, including metals, or` it may be so formed as tohav'e a peripheral portion of metal. Such an oiling wheel does not take up an excess ofoil from the wick, but only such as will cling to the wheel by capillary j attraction and such oil is transferred tothe v, guide rail, producing thereon only an exftremely thin film of oil, but ampleY for the "urpose while an excess of oil is returned to the wick,to be wiped off from. the roller bythe wick.

AThe result is that only suiiicient oilis transferred to the guide -rail Vto keepjthe latter in a properly lubricated condition, a vvery thin film of oil being suitable for the purpose. There is, therefore, no

.p waste of oil and a very economical use of oil. Whenever access to the interior Yof the .reservoir is desired, it is only necessary to ythe reservoir may each be bodilyremoved without the necessityof toolsV or the unfastening of any holdingdevices.

It will be observed that the roller, which may be taken as indicative of one or more rollers, has a pendulum mounting imparting to it the constant tendency to move into engagement with the guide rail and to follow up or yield to all side movements of the elevator. Furthermore, Vthe oil feeding wheel 22 being of a non-absorptive material carries the'lubricant by capillary attraction only and hence is inactive to convey the oil from the reservoir or wick to the guide rail when the elevator is standing still.

What is claimed is i l f 1. A lubricating device for the guide rails of elevators, comprising a reservoir for lubricating material adapted to be mounted on an elevator car, a transfer roller for the lu.- bricating material pendently mounted in and extending tothe exterior of the reservoir' and having its center ofggravity in the installed position of thedeviceon that side of the vertical lineof the 'axis' of swing of the pendulous mounting remote from the vrespective guide rail, whereby the roller has a constant tendency to gravitatetoward said guide roller, and lubricant feeding means within the reservoir in position to carry lubricant' fromV a supply thereof inthe reservoir to the said transferroller. Y
